Plasterers Insurance: Cover for Plastering, Rendering & Drylining

Reviewed by Matthew Bartlett, Director, Apex Insurance Brokers Limited · Last reviewed 2026-08-06

What insurance does a plasterer actually need?

Plastering sits in an awkward spot for insurance: it’s a wet trade carried out inside finished or half-finished properties, often at height, often around other people’s flooring, joinery and furniture. That combination shapes the covers that matter. A typical plasterer’s policy is built from a handful of parts:

• Public liability — injury to other people or damage to their property arising from your work. The core of the policy for almost every plasterer.
• Employers’ liability — legally required once you employ anyone, including most labour-only subcontractors.
• Tools cover — trowels, mixers, stilts, lasers and the rest, including theft from a locked van subject to the policy’s security conditions.
• Hired-in plant — your legal responsibility for hired mixers, spray machines, towers and drying equipment.
• Personal accident — an income if an injury stops you working, which matters when you’re self-employed with no sick pay.

Only one of those is required by statute — employers’ liability, and only when you have staff. Everything else is contractual or practical. But “not legally required” and “optional in practice” are very different things, as the next section explains.

Is public liability insurance a legal requirement for plasterers?

No. There is no law that says a plasterer must hold public liability insurance. In practice, though, you’ll struggle to trade without it. Main contractors and site managers routinely ask to see your certificate before you’re allowed on site — usually specifying a minimum limit in the subcontract or site induction paperwork. Housebuilders and commercial fit-out firms tend to want £5m. Letting agents and housing associations often ask for evidence before approving you for maintenance work. Even domestic clients increasingly ask, because their own home insurer may expect tradespeople working in the property to be insured.

So the honest framing is this: public liability is a commercial requirement rather than a legal one. The legal compulsion in this trade attaches to two other covers — employers’ liability once you take anyone on, and motor insurance for the van under the Road Traffic Act 1988. Keep those three categories straight and you’ll never be caught out by a site gate or a contract clause you didn’t see coming.

What does public liability actually cover on a plastering job?

The claims that reach us from wet trades follow recognisable patterns. Spillage and splash damage is the classic: a bucket of finish kicked over on a carpeted landing, gauging water tipped across an engineered floor, render splatter baked onto a neighbour’s car or windows during external work. Water damage is its close cousin — mixing water finding its way through floorboards into the ceiling below, or a re-skimmed bathroom wall hiding a nicked pipe that shows itself a week later.

Then there’s injury to people who aren’t part of your team. A homeowner trips over a hop-up or an extension lead you’ve run through a hallway. A dust sheet slides on a laminate floor. Debris comes off a scaffold during external rendering and strikes someone below. Boards being carried through an occupied house catch a person, a radiator or a glazed door. None of these need negligence on a grand scale — a moment’s ordinary inattention is enough for a claim, and defence costs alone can be significant even where you did nothing wrong. Public liability picks up both the compensation and the legal costs of defending you.

One important boundary: public liability covers damage your work causes to other things. It does not pay to redo the plastering itself if it cracks, blows or fails — more on that below.

When is employers’ liability legally required?

The moment you employ someone. Under the Employers’ Liability (Compulsory Insurance) Act 1969, an employer must hold employers’ liability insurance to cover injury or illness an employee suffers because of their work. The legal minimum limit is £5m, though policies are generally written above that, and you must be able to show your certificate. The requirement is enforced by the Health and Safety Executive.

The part plasterers most often get wrong is who counts as an employee. It is not just people on PAYE. An apprentice counts. A labourer you pay day rates counts. And — crucially in this trade — a labour-only subcontractor usually counts too: if you supply the materials, direct the work and they bring only their labour and hand tools, insurers (and the law) will generally treat them as your employee, whatever their tax status under the Construction Industry Scheme. A bona fide subcontractor — someone working under their own direction, with their own materials, plant and their own insurance — is treated differently, but insurers will expect you to check and record that their cover exists.

If you’re a genuine one-person band, employers’ liability isn’t compulsory. But the first time you bring a mate in to help board out a ceiling for cash, the legal duty can already have attached. If your labour arrangements vary job to job, tell your broker — it’s a cheap conversation compared with the alternative.

What about my tools, plastering machines and materials?

A working plasterer’s kit adds up faster than most people expect: stainless trowels and spatulas, a decent mixer or two, stilts, laser levels, screw guns for boarding, and for some firms projection or spray plastering machines that run into serious money. Tools cover insures this kit against theft and damage — but the details matter more than the headline sum.

Read the overnight conditions before you buy. Most policies cover theft from a vehicle only where there’s evidence of forced entry, and many restrict or exclude theft from an unattended van overnight unless it’s garaged, in a locked compound or fitted with specified security. If your van sleeps on the street with your kit inside — as it does for a lot of plasterers — you need a policy whose conditions match that reality, not one that quietly assumes the tools come indoors every night.

Hired kit is a separate question. When you hire a mixer, a spray machine, an alloy tower or drying equipment, the hire terms typically make you responsible for it while it’s in your care — hired-in plant cover deals with that. And if you’re carrying significant materials on site — boards, beads, bagged plaster, render for a big elevation — contract works cover can protect the unfinished job and materials against damage before handover. Worth discussing if you take on larger new-build or refurbishment contracts rather than day-rate domestic work. You can set all of this out in one go when you start a quote online.

What limit should I choose — £1m, £2m or £5m?

These figures are illustrative options rather than prices, but they map neatly onto how plasterers actually work. A sole trader doing domestic skimming and small repairs might start at £1m or £2m. The moment your work involves sites — new-build plots, commercial fit-outs, work for main contractors — check the paperwork, because £5m is a common contractual minimum and turning up with less can mean being turned away at the gate. Local authority and housing association frameworks frequently specify limits too.

Our advice is to choose the limit based on the worst realistic claim, not the typical one. Plastering claims are usually modest — a floor, a ceiling below, a stained sofa. But an injury claim involving a fall, or fire damage traced back to drying equipment left running, can be a different order of magnitude. The step up between limits is often smaller than people assume, and it’s the kind of decision a broker can talk through in five minutes with your actual work pattern in front of them.

Do renderers and dryliners need anything different?

Same family of covers, different emphasis. External rendering pushes you up ladders, towers and scaffolds, and insurers care about height: most trade policies carry a maximum working height, and exceeding it without telling your insurer can leave a claim unpaid. If you render gable ends or work on three-storey elevations, make sure the policy’s height limit reflects it. Machine-applied render brings the plant questions from the previous section into play, plus overspray — protecting neighbouring cars, windows and boundaries is where renderers’ liability claims tend to come from.

Drylining and boarding work is more likely to be site-based and labour-heavy: teams on price, CIS labour, main contractor requirements. That makes the employers’ liability question and the £5m public liability minimum the live issues, along with correctly describing your split of work when you buy — a policy rated for solo domestic skimming won’t respond well to a claim from a four-person drylining gang on a commercial site. Describe what you actually do; it’s the cheapest risk management there is.

What won’t plasterers insurance cover?

Fair question, and worth answering plainly. The big one is your own workmanship. If a skim coat crazes, a wall blows or render cracks and debonds, liability policies don’t pay to redo your own work — that’s treated as a business cost, not an insured event. What the policy can respond to is damage that defective work goes on to cause to other property — the distinction between re-rendering a wall (not covered) and the damage caused when a section of failed render falls onto something below (potentially covered) is one your broker should walk you through, because wordings differ.

Other common gaps: tools stolen from an unlocked or unattended vehicle outside the policy’s conditions; work above the policy’s stated height limit; injury to your own staff if you skipped employers’ liability; and your own injuries, which need personal accident cover rather than public liability. None of these are traps if you know they’re there — they’re traps when a policy is bought on price alone and read for the first time after the claim.

Does my van come into this?

Yes, but under a separate legal heading. Motor insurance is compulsory under the Road Traffic Act 1988 for any vehicle used on the road, and a van used for work needs to be insured for business use — not social, domestic and pleasure. Two practical points trip plasterers up. First, carrying materials and tools to jobs is commercial use; make sure the motor policy says so. Second, the van policy generally does not cover the tools inside it — that’s the job of the tools section of your trade policy, which is exactly why its overnight security conditions deserve a careful read.
